Vokera Evolve CO fault

by Adymould » Wed Dec 22, 2021 5:31 pm

Hi everyone, I have a 4 month old Vokera Evolve combi fitted in my garage which has no doors fitted and completely open. The combi is naturally using a balanced flue, but my reason for mentioning no doors on the garage is to illustrate that the boiler couldn’t be more ventilated.
Every 4 days or so the boiler trips off line due to a CO warning. It is easily reset within seconds and will answer all DHW and heating demands for another 3 days or so before tripping again.
Any thoughts? Many thanks.

Hi there,
The same Vokera Evolve CO fault code also mentions Combustion Failure, which has been my problem with the same model.
The real problem turned out to be a dirty burner, due to dusty conditions.
An easy fix, to remove and clean the fine mesh on the inside of the burner.
